By chance, the protagonist got a broken system. It didn’t matter, though. A broken system turned out to be better! By posting his own quests, whenever and however he wanted, the protagonist was heavily rewarded each time when a quest was completed. “I’m going to catch 10 mice tonight.” “Ding! Quest posted. Quest: The host will kill 10 mice in 24 hours: 0/10 Reward: The reward system is analyzing the difficulty of the quest. The rewards will be generated later.”
